FYI Another way MIDI is humanized in DAWs is in the temporal domain (i.e., rhythm/timing). This was popularized by Ableton's Groove Pool [1].
This was a feature in Cubase on Atari years before Ableton even existed. Most likely also in Logic Pro’s precursor Notator.
If you work on something for 5 years, adding a quick demo isn't too much to ask for, is it? I'm sure I'm not the only one who has negative time to spare.

Why not just upload it to pypi so you can do all this with one pip command?
